Description

Vehicle transport device

Technical Field

The present disclosure relates to a vehicle conveyance device that conveys a four-wheeled vehicle.

Background

Jp 2019-078099 a discloses a lifting/lowering/conveying carriage capable of supporting, lifting, and conveying a vehicle by using a small-capacity actuator by simply forming a device structure. The lifting/lowering conveyance carriage supports the tires of the vehicle by the arm portion and moves while lifting the vehicle, thereby conveying the vehicle.

In international publication 2016 and 189233, a transfer device for moving a four-wheeled vehicle is disclosed. The conveying device comprises a chassis, and the chassis is provided with a movable arm capable of being stored. Here, the chassis has a stretchable structure and is constituted by two divided bodies (segments) each including a pair of arms. The split body is movable between a position where the movable arm does not contact the wheel and a position where the movable arm contacts the tread of the wheel.

Disclosure of Invention

As disclosed in japanese patent application laid-open No. 2019 and 078099, there has been proposed a vehicle transport device (lifting transport carriage) in which a carriage part (carriage frame) is inserted under a four-wheeled vehicle, an arm group (arm) provided in the carriage part is brought into contact with each wheel to support the vehicle, and the carriage part is lifted up to lift the vehicle, and the vehicle transport device is moved in this state to transport the vehicle. When a plurality of vehicles of different types are transported by such a device, it is necessary to adjust the position of the arm that abuts against the wheel in accordance with the position of the wheel of each vehicle.

In international publication 2016 and 189233, the carriage part (chassis) has a telescopic structure and is composed of two divided bodies. Thus, the position of an arm (movable arm) that supports the wheel can be adjusted by moving the divided body. However, if a mechanism that partially expands and contracts the carriage unit in this way is adopted, the apparatus becomes large when the carriage unit is configured to ensure rigidity for transporting the vehicle.

The present disclosure provides a vehicle transport device capable of adjusting the position of an arm that abuts a wheel of a vehicle without partially extending and contracting a carriage unit.

A vehicle transport apparatus according to an aspect of the present disclosure is an apparatus for transporting a four-wheeled vehicle having a pair of front wheels and a pair of rear wheels. The vehicle conveying device comprises: a bogie portion inserted under the vehicle in a front-rear direction of the vehicle; and an arm group provided to the carriage unit. The arm set includes a first arm set that supports a pair of first wheels that are one of the pair of front wheels and the pair of rear wheels, and a second arm set that supports a pair of second wheels that are the other of the pair of front wheels and the pair of rear wheels. The vehicle transfer device further includes: a first arm actuator connected to the first arm group and operated to switch between a support state in which the first arm group is in contact with the first wheel and a release state in which the first arm group is not in contact with the first wheel; a second arm actuator connected to the second arm group and operating to switch between a support state in which the second arm group is in contact with the second wheel and a release state in which the second arm group is not in contact with the second wheel; and sliding members which are respectively arranged on two side surfaces of the trolley part and slide along the length direction of the trolley part independently from the trolley part. The first arm group and the first arm actuator are coupled to the slide member, integrated with the slide member, and configured to slide in the longitudinal direction of the carriage independently of the carriage. The vehicle transport device transports the vehicle by moving the first arm group and the second arm group in a state where the first arm group and the second arm group respectively abut against the first wheel and the second wheel to support the vehicle and lift the vehicle by raising the cart unit.

In the vehicle transport device, the slide member may be configured to slide by being fitted into rail portions provided on both side surfaces of the carriage portion.

The vehicle transfer device may further include: a main body part which is arranged at one end of the trolley part, which is provided with the first arm group, in the length direction and provides a running function of the vehicle conveying device and a lifting function of the trolley part; and a slide actuator provided between the main body portion and the slide member and configured to slide the slide member. The slide actuator may include a rod-shaped movable portion coupled to the slide member and configured to slide the slide member by moving in a longitudinal direction of the carriage portion. The first arm group may include a fixed arm that abuts the first wheel on the side where the main body portion is provided. Here, the lower end portion of the fixed arm may be screwed to the slide member in a state of extending in a direction orthogonal to the longitudinal direction of the carriage portion. Further, a coupling portion of the slide member and the movable portion of the slide actuator may be positioned more inward than a screwing portion of the slide member and the fixed arm in a direction orthogonal to the longitudinal direction of the carriage portion.

In the vehicle transporting device described above, the slide member may have a plurality of ribs, and the screw portion of the slide member and the arm may be sandwiched by the ribs.

The vehicle transfer device may further include a top plate coupled to the first arm group and the slide member. The top plate may be configured to slide along the longitudinal direction of the carriage unit integrally with the slide member and independently of the carriage unit.

In the vehicle handling device described above, the slide member may have a plurality of ribs, and the top plate and the slide member may be joined by the ribs.

The vehicle transport device may further include a protection member for protecting the wire harness for supplying power to each arm actuator. The wire harness protection member may be coupled to the slide member, and configured to be integrated with the slide member and to slide in the longitudinal direction of the carriage portion independently of the carriage portion.

According to the vehicle transport apparatus of the present disclosure, the first arm group and the first arm actuator slide along the longitudinal direction of the carriage unit independently of the carriage unit. Thus, the position of the arm can be adjusted to match the wheel position of the vehicle without partially extending or contracting the carriage unit. Further, the vehicle transport apparatus may employ a mechanism capable of adjusting the position of the arm without increasing the size of the apparatus.

Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, when the number, the amount, the range, or the like of each element is mentioned, the concept of the present disclosure is not limited to the mentioned number unless it is specifically indicated or it is clear from the principle that the number is determined. In addition, the configuration and the like described in the embodiments shown below are not necessarily essential to the concept of the present disclosure, except for the case where the configuration is specifically shown or the case where the configuration is clearly understood in principle. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and their repetitive description will be appropriately simplified or omitted.

1. Vehicle transport device

Fig. 1 is a perspective view of a vehicle conveying device 10 according to the present embodiment. The vehicle transfer device 10 includes a main body 100, a carriage 200, a first arm group 211, a second arm group 212, a first arm actuator 221, and a second arm actuator 222. The main body 100 is provided at one end of the carriage 200 on the side where the first arm group 211 is provided in the longitudinal direction.

The vehicle transport apparatus 10 inserts the carriage unit 200 downward of the vehicle in the front-rear direction of the four-wheeled vehicle, and supports the vehicle by bringing the first arm group 211 and the second arm group 212 provided in the carriage unit 200 into contact with the front wheels and the rear wheels of the vehicle, respectively. The vehicle conveying apparatus 10 moves in a state where the carriage unit 200 is raised to lift the vehicle, thereby conveying the vehicle.

Typically, the vehicle transfer device 10 is inserted into the truck unit 200 from the front of the vehicle. That is, the first arm group 211 abuts against the front wheels of the vehicle and the second arm group 212 abuts against the rear wheels of the vehicle, thereby supporting the vehicle. However, the carriage unit 200 may be inserted from the rear of the vehicle to support the vehicle.

In the following, as shown in fig. 1, the direction in which the body portion 100 is provided is referred to as a first direction, a direction located rearward with respect to the first direction is referred to as a second direction, a direction located leftward with respect to the first direction is referred to as a third direction, and a direction located rightward with respect to the first direction is referred to as a fourth direction with respect to the direction of the vehicle transfer device 10. Hereinafter, the wheel of the vehicle positioned in the first direction when the carriage unit 200 is inserted into the lower portion of the vehicle is also referred to as a "first wheel" and the wheel of the vehicle positioned in the second direction is also referred to as a "second wheel".

The main body 100 includes a driving wheel 110 providing a traveling function of the vehicle transfer device 10 and a lifting device 120 providing a lifting function of the carriage unit 200. The drive wheel 110 and the lifting device 120 are typically operated by actuators. Here, the mechanism of the lifting device 120 is not limited. For example, the carriage unit 200 may be raised and lowered by a hydraulic cylinder, or the carriage unit 200 may be raised and lowered by an air spring.

The main body 100 includes a power source and a control device, which are not explicitly shown in fig. 1. The power source supplies power to various actuators provided in the vehicle transport apparatus 10. Typically, a battery serving as a power source is electrically connected to each actuator via a harness to supply electric power. In the following description, the power source is assumed to be a battery and power is supplied to each actuator via a wire harness.

The control device outputs control signals for driving and controlling various actuators provided in the vehicle conveying device 10. The actuator operates in accordance with the control signal. The control device is configured to be able to transmit information to each actuator. Typically, the control device is electrically connected to each actuator by a wire harness. However, it may be formed by other methods. For example, the information may be transmitted by wireless communication or optical communication.

The control device may be a device provided outside the vehicle transfer device 10. In this case, the control device is configured to be able to transmit information to each actuator by communication.

The first arm group 211, the second arm group 212, the first arm actuator 221, and the second arm actuator 222 are provided in the carriage unit 200.

First armset 211 includes arm AM11, arm AM12, arm AM13, and arm AM 14. The arm AM11 is paired with the arm AM13 and abuts in a manner of sandwiching a first wheel (e.g., left front wheel). The arm AM12 is paired with the arm AM14 and abuts against the first wheel (for example, the right front wheel) in a sandwiched manner.

Second armset 212 includes arm AM21, arm AM22, arm AM23, and arm AM 24. The arm AM21 is paired with the arm AM23 and abuts against a second wheel (e.g., a left rear wheel). The arm AM22 is paired with the arm AM24 and abuts against a second wheel (for example, a right rear wheel).

Thus, the first arm group 211 and the second arm group 212 support the vehicle by coming into contact with the respective wheels.

The first arm actuator 221 is an actuator connected to the first arm group 211 and operated to switch between a support state in which the first arm group 211 is in contact with the first wheel and a release state in which the first arm group 211 is not in contact with the first wheel. The second arm actuator 222 is an actuator connected to the second arm group 212 and operated to switch between a support state in which the second arm group 212 is in contact with the second wheel and a release state in which the second arm group 212 is not in contact with the second wheel. Hereinafter, the first arm actuator 221 and the second arm actuator 222 are collectively referred to as "arm actuators" except for the case where they are distinguished.

Fig. 2A and 2B are diagrams for explaining the operation of the arm actuator (the first arm actuator 221 or the second arm actuator 222). Fig. 2A shows the arm AM and the arm actuator in the released state, and fig. 2B shows the arm AM and the arm actuator in the supported state. The arm actuator has a rod RD coupled to the arm AM at a position CP and a cylinder CL that houses the rod.

The arm actuator moves the rod RD in the axial direction of the working cylinder CL. When rod RD is pushed out, arm AM rotates about position PV1, and cylinder CL rotates about position PV 2. When rod RD is pulled in, arm AM and cylinder CL rotate in the opposite direction to when rod RD is pushed out. Thus, the arm AM operates to change from the released state to the supported state or from the supported state to the released state.

The arm AM (the arms AM11 and AM12 in fig. 1, and hereinafter also referred to as a "fixed arm") that constitutes the first arm group 211 and that abuts the first wheel on the side where the main body portion 100 is provided is not connected to the first arm actuator 221 and is fixed in a state of extending in a direction (the third direction or the fourth direction in fig. 1) orthogonal to the longitudinal direction of the carriage unit 200. The fixing method will be described later.

Next, operations related to the conveyance of the vehicle 1 by the vehicle conveying device 10 according to the present embodiment will be described with reference to fig. 3A, 3B, 4A, and 4B. Here, the vehicle conveying device 10 is inserted into the carriage unit 200 from the front of the vehicle 1.

Fig. 3A and 3B are plan views of the vehicle transfer device 10, and show examples of operations for supporting the vehicle 1. As shown in fig. 3A, the vehicle transfer apparatus 10 inserts the carriage unit 200 from the front of the vehicle 1 to the lower side of the vehicle 1 with the first arm group 211 and the second arm group 212 in the released state. At this time, the fixed arm (arm AM11 and arm AM12) abuts against the first wheel (front wheel FW of the vehicle 1). As shown in fig. 3B, the first arm group 211 and the second arm group 212 are brought into a supporting state, whereby the first arm group 211 and the second arm group 212 respectively abut against the first wheel and the second wheel (the front wheel FW and the rear wheel RW of the vehicle 1) to support the vehicle 1.

Fig. 4A and 4B are side views of the vehicle transfer device 10, and show an example of the operation of lifting the vehicle 1. As shown in fig. 4A and 4B, the vehicle transfer apparatus 10 raises the vehicle 1 by raising the carriage unit 200 by the lift device 120 in a state where the vehicle 1 is supported by the first arm group 211 and the second arm group 212.

Here, as shown in fig. 4B, the wheels 230 of the carriage unit 200 are configured to be able to contact the ground and roll even in a state where the carriage unit 200 is lifted. For example, the vehicle transfer device 10 includes an actuator that operates to maintain the position of the wheels 230 with respect to the elevation of the carriage unit 200. A plurality of wheels 230 may be provided at positions different from those shown in fig. 4A and 4B.

The vehicle transportation device 10 transports the vehicle 1 by moving in a state where the vehicle 1 is lifted up.

2. Sliding mechanism

As described above, in order to lift the vehicle 1, the vehicle transfer device 10 needs to support the vehicle 1 by bringing the first arm group 211 and the second arm group 212 into contact with the first wheel and the second wheel, respectively. On the other hand, the vehicle transporting apparatus 10 is assumed to transport a plurality of vehicles 1 of different types. In this case, it is considered that the positions of the first wheel and the second wheel are different depending on the vehicle 1 to be transported. Therefore, the vehicle transfer apparatus 10 needs to adjust the position of the first arm group 211 or the second arm group 212 in accordance with the positions of the first wheel and the second wheel of the vehicle 1 to be transferred.

The vehicle transfer device 10 of the present embodiment includes a slide mechanism that slides the first arm group 211 and the first arm actuator 221 along the longitudinal direction of the carriage unit 200 independently of the carriage unit 200.

Fig. 5A and 5B show examples of the sliding of the first arm group 211 and the first arm actuator 221. Fig. 5A and 5B show two examples of the sliding states of the first arm group 211 and the first arm actuator 221. In fig. 5B, the first arm group 211 and the first arm actuator 221 slide in the second direction along the longitudinal direction of the carriage unit 200, as compared with fig. 5A. Here, the carriage unit 200 does not extend and contract, and the first arm group 211 and the first arm actuator 221 slide independently of the carriage unit 200.

In this way, the vehicle transfer device 10 according to the present embodiment is configured such that the first arm group 211 and the first arm actuator 221 are slidable along the longitudinal direction of the carriage unit 200 independently of the carriage unit 200.

The slide mechanism of the vehicle transfer device 10 according to the present embodiment will be described in detail below.

2-1 structure of sliding mechanism

Fig. 6A and 6B are diagrams for explaining the structure of the slide mechanism of the vehicle transport device 10. Fig. 6A and 6B show portions of the vehicle transfer device 10 near the first arm group 211 and the first arm actuator 221. Fig. 6A shows the appearance of this portion, and fig. 6B shows the internal structure of the top plate 240 and the cover CVR with the top plate and the cover removed. Here, the cover CVR is a member for protecting the device inside to improve the maintainability of the vehicle transfer device 10. The top plate 240 will be described later.

As shown in fig. 6B, the vehicle transfer device 10 includes a slide member 250 and a slide actuator 260.

The slide members 250 are provided on both side surfaces of the carriage unit 200. The slide member 250 is configured to be slidable in the longitudinal direction of the carriage unit 200 independently of the carriage unit 200. The structure of the slide member 250 will be described later.

The slide actuator 260 is an actuator for sliding the slide member 250. The sliding state of the sliding member 250 changes by the operation of the sliding actuator 260. The operation of the slide actuator 260 will be described later. The action of the slide actuator 260 is typically controlled by a control device.

The first arm set 211 and the first arm actuator 221 are coupled to the sliding member 250. Therefore, the sliding member 250 slides, whereby the first arm group 211 and the first arm actuator 221 slide integrally with the sliding member 250. Further, the first arm group 211 and the first arm actuator 221 slide along the longitudinal direction of the carriage unit 200 independently of the carriage unit 200.

Here, when the first arm actuator 221 slides in the second direction along the longitudinal direction of the carriage unit 200 along with the sliding of the sliding member 250, a part of the harness HNS that supplies power to the first arm actuator 221 is exposed. Further, there is a possibility that the maintainability of the vehicle transfer device 10 is reduced.

Therefore, the vehicle conveying device 10 of the present embodiment includes the harness protection member 270 for protecting the wire harness HNS. In addition, the wire harness protective member 270 is combined with the sliding member 250. Thus, the sliding member 250 slides, whereby the wire harness protective member 270 slides integrally with the sliding member 250. Further, the wire harness protection member 270 slides along the longitudinal direction of the carriage part 200 independently of the carriage part 200. This prevents the harness HNS from being exposed due to the sliding of the first arm actuator 221, and improves the maintenance of the vehicle conveying device 10.

As shown in fig. 6A, the vehicle handling device 10 has a ceiling 240. The top plate 240 is coupled to the first arm group 211 and the sliding member 250. This can improve the rigidity of the first arm group 211 and the slide member 250 with respect to the load received from the vehicle 1. The top plate 240 is coupled to the first arm group 211 and the slide member 250 as a single body without being separated from each other on both side surfaces of the carriage unit 200. This can increase the area for receiving the load of the vehicle 1, and can improve the rigidity against the load received from the vehicle 1.

Here, the top plate 240 is coupled to the first arm group 211 and the slide member 250 but not coupled to the carriage unit 200. Thus, the sliding member 250 slides, whereby the top plate 240 slides integrally with the sliding member 250. Further, the top plate 240 slides along the longitudinal direction of the carriage part 200 independently of the carriage part 200.

Fig. 7A and 7B show examples of sliding of the vehicle handling device 10 by the sliding mechanism. Fig. 7A and 7B show portions of the vehicle transfer device 10 near the first arm group 211 and the first arm actuator 221, for the case of fig. 7A and 7B in which the sliding state of the slide member 250 is different. Fig. 7B is a state in which the slide member 250 slides in the second direction along the longitudinal direction of the carriage unit 200 as compared with fig. 7A.

As shown in fig. 7A and 7B, the sliding member 250 slides, whereby the first arm group 211, the first arm actuator 221, and the top plate 240 slide in the longitudinal direction of the carriage unit 200 independently of the carriage unit 200. Similarly, the wire harness protecting member 270 slides to prevent the wire harness HNS from being exposed.

2-2. action of sliding actuator

Fig. 8A and 8B are diagrams for explaining the operation of the slide actuator 260. Fig. 8A and 8B are views equivalent to fig. 6B, and show different sliding states of the sliding member 250.

The slide actuator 260 includes a rod-shaped movable portion MP that moves in the longitudinal direction of the carriage unit 200. The movable portion MP is coupled with the slide member 250. As shown in fig. 7A and 7B, the slide actuator 260 slides the slide member 250 so as to be pushed in or pulled out by the movable portion MP moving in the longitudinal direction of the carriage unit 200.

2-3 structure of sliding member

Fig. 9 is a diagram for explaining the structure of the slide member 250. Fig. 9 shows a portion of the vehicle handling device 10 provided near the slide member 250 on the side surface of the truck portion 200 in the third direction. Here, the slide member 250, the arm AM11, the movable portion MP of the slide actuator 260, and the cart unit 200 are illustrated, and other components of the vehicle conveying apparatus 10 are omitted.

The slide member 250 is constituted by a slide portion 251 and an engaging portion 252.

The sliding portion 251 is a portion that provides a sliding function of the sliding member 250. As shown in fig. 9, the slide portion 251 is fitted into the rail portions RAL provided on both side surfaces of the carriage portion 200, and slides along the rail portions RAL. Typically, sliding portion 251 is fitted to track portion RAL via rolling elements such as balls and cylindrical rollers, and slides by rolling of the rolling elements.

By configuring such that the sliding portion 251 is fitted into the rail portions RAL provided on both side surfaces of the carriage unit 200 to slide, the space above and below the carriage unit 200 required for installation of the sliding mechanism can be suppressed. Further, the height of the carriage unit 200 can be suppressed, and the range of the vehicle height of the transportable vehicle 1 can be expanded.

The engaging portion 252 is a portion that is mounted in conjunction with the first arm group 211, the first arm actuator 221, and the like. The engaging portion 252 is integrated with the sliding portion 251. As shown in fig. 8A, 8B, the engaging portion 252 has a plurality of ribs RB.

The top plate 240 is combined with the slide member 250 by the rib RB. This allows the load of the vehicle 1 to be equally distributed in the sliding member 250. Further, in a state where the arm AM that rotates so as to switch between the support state and the release state is attached to the slide member 250, the load on the rotation shaft (position PV1) of the arm AM can be reduced.

The rib RB has a recess for passing the power supply harness HNS therethrough. However, the ribs RB are not separated by the recesses. In this way, by the rib RB having the concave portion without being separated, it is possible to pass the wire harness HNS while suppressing a decrease in rigidity of the engagement portion 252. Further, the top plate 240 is coupled to the rib RB at the opposite side of the recess of the rib RB.

The arm AM11 is a fixing arm, and a lower end portion thereof is screwed to the engaging portion 252 in a state of extending in the third direction. Thereby, the arm AM11 is fixed in a state of extending in a direction orthogonal to the longitudinal direction of the carriage unit 200. Here, as described above, the arm AM11 is not connected to the first arm actuator 221. Further, in order to ensure a place for installing the slide actuator 260 and the wire harness protective member 270 by sliding integrally with the slide member 250, the arm AM11 cannot support the arm AM11 with a suspension. Therefore, the arm AM11 may not have sufficient rigidity against the load received from the vehicle 1, and the stress may not be sufficiently reduced.

Therefore, in the vehicle transport apparatus 10 according to the present embodiment, as shown in fig. 9, the coupling portion between the slide member 250 and the movable portion MP of the slide actuator 260 can be configured to be the inner side of the coupling portion 252 in the direction orthogonal to the longitudinal direction of the carriage unit 200, and the screw-engagement portion of the arm AM11 can be provided on the outer side of the coupling portion 252. This reduces the bending moment applied to the arm AM 11. Further, the screw portion of the arm AM11 is sandwiched by the rib RB. This can increase the rigidity of the arm AM 11. In this way, the stress generated in the arm AM11 can be sufficiently reduced.

Note that, a member to be a packing may be sandwiched between the screw-threaded portion and the rib RB, so that the screw-threaded portion of the arm AM11 may be sandwiched by the rib RB.

The structure of the slide member 250 described in fig. 9 is common to the slide members 250 provided on both side surfaces of the carriage unit 200. That is, the structure of the slide member 250 provided on the fourth direction side surface of the carriage unit 200 is equivalent to the structure described in fig. 9. In this case, the fixing arm screwed with the joint portion 252 becomes the arm AM 12.

Fig. 10 is a plan view of a slide mechanism portion of the vehicle handling device 10. Fig. 10 shows a half of the carriage part 200 in the third direction. Here, the half of the carriage unit 200 in the fourth direction is shown similarly to being symmetrical to fig. 10.

As described above, the arm AM, the first arm actuator 221, the movable portion MP of the slide actuator 260, and the wire harness protective member 270 are mounted in combination with the engagement portion 252 of the slide member 250. The wire harness HNS is configured to pass through the recess of the rib RB.

Here, as shown in fig. 10, the slide actuator 260 is connected to the carriage part 200 via an engagement member JNT. This makes it possible to equalize the deflection of the slide member 250 and the deflection of the entire slide actuator 260 with respect to the deflection caused by the load of the vehicle 1. Further, the movement of the movable portion MP of the slide actuator 260 can be prevented from being hindered by the flexure, and smooth operation can be achieved.

3. Effect

As described above, according to the vehicle transfer device 10 of the present embodiment, the first arm group 211 and the first arm actuator 221 slide along the longitudinal direction of the carriage unit 200 independently of the carriage unit 200. Thus, the position of the arm AM can be adjusted to match the position of the wheel of the vehicle 1 without locally extending or contracting the carriage unit 200. Further, the vehicle transfer device 10 may employ a mechanism capable of adjusting the position of the arm AM without increasing the size of the device.

Next, according to the vehicle transport apparatus 10 of the present embodiment, the slide mechanism is configured such that the slide portion 251 of the slide member 250 is fitted into and slides on the rail portions RAL provided on both side surfaces of the carriage unit 200. This can suppress the space above and below the carriage unit 200 required for installing the slide mechanism. Further, the height of the carriage unit 200 can be suppressed, and the range of the vehicle height of the transportable vehicle 1 can be expanded.

Next, according to the vehicle transport device 10 of the present embodiment, the lower end portions of the fixing arms (the arms AM11 and AM12) are screwed into the slide member 250 in a state where the fixing arms extend in the direction orthogonal to the longitudinal direction of the carriage unit 200. Here, a coupling portion of the slide member 250 and the movable portion MP of the slide actuator 260 is an inner side of the engaging portion 252 in a direction orthogonal to the longitudinal direction of the carriage portion 200, and a screw portion of the slide member 250 and the fixed arm is an outer side of the engaging portion 252. That is, the coupling portion between the slide member 250 and the movable portion MP of the slide actuator 260 is positioned more inward than the screwing portion between the slide member 250 and the fixed arm in the direction orthogonal to the longitudinal direction of the carriage unit 200. In addition, the fixing arm is sandwiched by the ribs RB of the engaging portion 252. This can increase the rigidity of the fixing arm with respect to the load received from the vehicle 1, and can reduce the stress generated in the fixing arm.

Next, the vehicle transfer device 10 according to the present embodiment includes the top plate 240 coupled to the first arm group 211 and the slide member 250. Here, the top plate 240 is combined with the rib RB of the engaging portion 252. This can increase the rigidity of the first arm group 211 and the slide member 250 with respect to the load received from the vehicle 1, and can reduce the load on the rotation shaft of the arm AM. In addition, the top plate 240 is slidable integrally with the slide member.

Next, the vehicle conveying device 10 according to the present embodiment includes the wire harness protection member 270, and the wire harness protection member 270 is coupled to the slide member 250. This can prevent the harness HNS from being exposed due to the sliding of the first arm actuator 221, and can improve the maintainability of the vehicle conveying device 10.
